That horrible search function not working?
Right after your thread http://www.gamesas.com/index.php?/topic/1104160-lyrondorss-dealy-reflex-lols comes up - in fact I only looked at yours because I thought more was being added to that thread.
I've seen Lyrondor's conflict with other combat overhauls but not severely - if you see twitching actors or archers who look like they are spinning in place then that would be an indication. Those are old bugs with Lyrondor's that were addressed, but sometimes creep in when used in conjunction with other combat AI type mods.
If only overhauls were not so inclusive. Frans gives the option to not have Lyrondor while OOO and MMM do not.
regardless I've not heard or seen of conflicts so heavy that it was game breaking.
